Application filed December 22, 1909. Serial No. 534,517.

To all 'whomz't may concern:

= Be it known that I, BERNHARD JOHN VAL- ENTINE ADOLPH FLUGEL,manufacturer, a subject of the King of Great Britain; residing at 2lLime street, in the city f 'Lond on7 England, have invented certain ne-wand useful Improvements in or Relating to TypeWVriting Machines, ofwhich the following is a specification.

This invention has for its object to provide type-writing machines witha special key-actuated carriage return` According to the presentinvention means for returning` the carriage are so combined andarranged-to act in conjunction with the typewriting machine that uponthe end ci. the line being reached (1'. c. upon the carriage reachingthe end of its travel to the left) thereuponv the return-key willrelease the carriage from the devices which normally hold the saidcarriage in posit-ion and also release or bring into operation theusuall motor by which the carriage is Vreturned along its guide-Ways tothe extreme right hand position for which the machine may be set for thetime being. The Aturning of the roller `for feeding the paper may thenbe separately and independently effected in the usual manner.

I will now proceed to describe my present invent-ion with reference tothe accompany ing drawings, in which the figure shows a side elevationof the invention.

The toothed wheel A adapted to rotate it'reely around the shaft (L isdrivenby any suitabley motor such as an ordinary spring clockwork motor(not shown) mounted on the main traine or other fixed part of thetypeuf'riting machine and this wheel A gears with the toothed wheel Badapted to rotate freely around the shaft Z) and this latter wheel B inturn gears with the smaller toothed 'wheel (l adapted to-rotate lfi'eelvaround the shaft c` in opposite direcA tioii to B. '.l`he.sha't'ts 'band c arelcarried 'in the yoke-ends or forked ends D1 D2 ofthevolte-lever or'roeking-leverD which latter is `vpivoted or adapted toroel; or turn 4mally kept pressed in one direction (i. e.' in

the direction of the. arrow vby the spring` E; and means are providedsuch as the rod F to force the end (Z of said rocking-lever Din theOPPOSite direction to said arrow ai; the spring E keeping 'said end CZofl said lever D forced againstthe collar or abutment f fixed on the rod-F which latter in turn has afixed limit of movement forming its normalposition and when in this normal position (as shown in the drawings) theend d of the rockingelever D is moved Jto its extreme right handposition against said abutnient f by the action of the spring E andthereby the toothed wheel B is forced into l gear with the teeth of therack H which is thereby moved alongin the direct-ion of the arrowy-space by space (i. e. one space at a time) as and when any key of thetype-A writing machine is operated; or a fixed number of spaces fortabulating purposes; while enforcing the end (Z of the rock lever D inthe .opposite direct-ion to the arrow ai' through the medium of the rodF thereby the toothed wheel B is moved out of gear with the toothedrackv H and the toothed wheel C simultaneously moved into gear with theteeth of said rack H which latter is thereupon caused t0 automaticallyreturn, in one movement. to fthe limit of its travel in the direction ofthe arrow z whereupon on releasing the rod F the spring E will rock'thelever D and move the toothed support carrying the platenor roller 'or'means over or against u'hiel'i. the paper or other material is holdwhile. boing struck by the type; for example these rack teeth may beformed in a rack-bar such as H and this rack bar lil` may he rigidlyfixed to the aforesaid traveling carriage (not shown) by `means of thearms orbraokets l and J.

ll a carriage retiirinltoy operating solely tor the purpose otaetiiatii'ig the returning means oi the carriage.

That l claim is:- f

l. A device et the cln'iraeler described,

comprising a rocking-lever adapted to be adapted to be engaged by eitherof said Y I toothed vtheels,'means for normally pressving' the rockinglever in one Adirection to' cause one of the toothed AWheels to 4engagethe rack, 'and means for moving at will the rocking lever in theopposite direction to cause the other toothed Wheel to engage the rack.

2* A deviee of the character described,

comprising a main-axle adapted to he` mounted G11-the frame of atypewriting ma-A chine, a drive gear Wheel rotatably mounted .with thedrive gear Wheel, a smaller toothed Wheel mounted at the end of theother arm and intermeshing with the larger toothed Wheel, a rack adaptedto be attached to the vtypewriter carriage and to be engaged by eitherof said toothed Wheels, a spring pressing against the end of the mainstem of the roeking-lever and causing one of said toothed 'Wheels tonormally engage said rack, and means for moving said main stem againstthe pressure of the spring to cause the other toothed Wheel to engagethe rack.
